IBM System Storage DS3000, Programming Manual

Page: 194 / 652

Parameter Description
userLabel
The name of the FlashCopy logical drive.
Enclose the FlashCopy logical drive name in
double quotation marks (“ ”). If you enter more
than one FlashCopy logical drive name, this
command fails.
warningThresholdPercent
The percentage of repository capacity at which
you receive a warning that the FlashCopy
repository logical drive is nearing full. Use
integer values. For example, a value of
70
means
70 percent. The default value is 50 .
repositoryFullPolicy The type of processing that you want to
continue if the FlashCopy repository logical
drive is full. You can choose to fail writes to the
base logical drive (
failBaseWrites
) or fail writes
to the FlashCopy logical drive (
failFlashCopy
).
The default value is
failFlashCopy
.
Notes
®
You can use any combination of alphanumeric characters, hyphens, and underscores for the names.
Names can have a maximum of 30 characters.
If you do not specify a value for the
warningThresholdPercent
parameter or the
repositoryFullPolicy
parameter, the previously set value is used.
Recreating Multiple FlashCopy Logical Drives without Optional Parameters
v
If you list multiple FlashCopy logical drives to be re-created but do not specify any of the optional
parameters, the re-create operation processes the FlashCopy logical drives as a "batch" process.
v
Before restarting any FlashCopy, validation checks for the necessary restarted preconditions of the
FlashCopy are performed. If any of the listed FlashCopy logical drives fail the validation, the entire
command fails and the FlashCopy logical drives are not re-created. If the validation is successful for all
of the FlashCopy logical drives in the list, but one or more of the legacy FlashCopies in the list fail to
restart, the entire command fails and none of the FlashCopies are re-created.
v
During FlashCopy recreation, all affected logical drives (FlashCopy, base, and repository) are
appropriately quiesced and I/O operations are resumed to all affected logical drives after all
FlashCopy are re-created.
Remove Logical Drive LUN Mapping
This command removes the logical unit number (LUN) mapping.
Syntax
remove (allLogicalDrives | logicalDrive [ logicalDriveName ] |
logicalDrives [ logicalDriveName1 ... logicalDriveNameN ] | accesslogicalDrive)
lunMapping (host=” hostName ” |
hostGroup=(“ hostGroupName ” | defaultGroup))
Parameters
Parameter Description
allLogicalDrives
This parameter removes the LUN mapping from all of the
logical drives.
